P2P technology allows computers to communicate without using a central server. Sun's Java-based P2P offering will allow services to be run across a distributed network of devices, from mobile phones right up to mainframes.
Mike Clary, vice-president of the Jxta project, said, "The Web is evolving in both depth and breadth into an 'expanded Web', which makes it challenging to efficiently communicate and access resources on the Internet.
"Sun is offering a unified approach to address the next phase of distributed computing, an approach that will enable users to quickly and easily find it, get it, use it."
Sun released Jxta under a licence that will allow users to extend the software with their own proprietary additions.
